Factory Bulk Orders
For OEM assembly lines and repeat production orders. Share batch quantity, annual demand, inspection requirements and delivery schedule.
Custom SEMS Assemblies
Screw and captive-washer assemblies configured to your application: head and drive, flat or spring washers, material and finish. Confirm washer dimensions and assembly details in your drawing.
SEMS Screws: Washer Configuration and Factory Ordering
Specify the complete assembly
SEMS ordering starts with the screw head, drive, thread and retained washer configuration. State whether you need a flat washer, a spring washer or a combination. Include washer inside diameter, outside diameter, thickness and order in the assembly.
Check the installed envelope
Check the space occupied by the head and washers, tool access and usable thread length against the mating parts. Retaining the washer helps keep components together during handling; it does not by itself establish resistance to loosening in your application.
Prepare a batch specification
Send a drawing or approved sample reference, material, finish, batch quantity and delivery schedule. Confirm inspection criteria and packing before production. If washer arrangement or coating changes, review the complete assembly again rather than ordering only by screw diameter.
